Forgot to post this, but there was recently a handful of enemies revealed for the upcoming game Dragon's Crown, and one of them is a busty vampire. She's pictured biting a female victim NPC who looks very similar to her, and it seems very likely that she'll turn NPCs into vampires too; I would not be surprised if they gain the same curvy shape as the vampire.
I also doodled a comic to go along with that very idea:
